I use a i7 CPU, and it is 6-core/12 threads. As a matter of fact,
Inkscape seem to support at maximum of 8 threads and a rendering cache
of up to 4098 MB. Is that limitation addressed? As far as zooming level
go, rasterization of filters is how Illustrator managed to keep their
rendering speed quick as possible. But, I don't think it'll help too
much with the current Inkscape as it is now. They also support GPU
acceleration. I wonder if that's within any reach of Inkscape as of now.
